Cadbury World has been added to the Merlin Annual Pass ahead of a previously-announced schedule.
Previously stated as being added from 2024, the chocolate-based Birmingham attraction can now be pre-booked by pass-holders.
Merlin Entertainments took over Cadbury World in January this year.
Entry to the attraction can now be pre-booked via the new booking hub, which was unveiled earlier this week.
Meanwhile, the Sandcastle Waterpark in Blackpool will remain outside the scope of the Merlin Annual Passes.
Merlin currently runs the waterpark under contract, but said that the situation would not change until ownership was transferred from Blackpool Council.
